This absolutely must be interrupted. On 25man, having two raid members in charge of interrupts (with a third member available as an emergency back-up) is effective.

Does mind numbing poison slow down the casting of this ability?

sadly, no. al forms of slowing casting speed do not work on him =[

Since 3.2 this seems to have changed somewhat. We figured out that the cooldown between each cast is 50% of the cooldown of the ability used to interrupt him.

So if a rogue uses kick (10 second cooldown) it means there is 5 seconds between each of his casts.If a shaman uses Wind Shear (6 second cooldown) it means there is 3 seconds between each of his casts.

It becomes really simple to interrupt therefore, if you use 2 people of the same class/spec.

Edit: This has been hotfixed as of 08/08/09. A blue post has said "General Vezax will now cast Shadow Crash slightly less frequently. He will also refrain from casting Searing Flames multiple times in succession."
